The parents want to know who's accountable for students left waiting in the cold for school buses they said never came. Tyler said her son stood outside for hours on Monday.

"He went out there right at 7:20 a.m., and stayed out there until 9 a.m.," Tyler said.

Tyler said she eventually had to leave work and drive across town to pick up her son at home and take him to school.

"By the time I made it here, no bus had shown up," Tyler said.

Danyelle Holmes said she was driving her daughter to school when she saw the kids waiting outside in freezing weather at the bus stop on Adkins Boulevard and Brentwood Drive.

"I noticed that students were sitting at the bus stop and shivering. I stopped to ask them if they needed a ride to school," Holmes said.

Parents said Jackson Public Schools usually calls with a recorded message when they need to update everyone.

"I think someone had dropped the ball somewhere along the road," Holmes said.

JPS responded to the parents' claims in a statement to 16 WAPT News.

"The JPS Transportation Department has experienced some delays in reaching bus stops on time over the past few days due to mechanical failures with some of its buses," JPS said. "The district apologizes to parents for the delays and is working to resolve its transportation challenges.

The parents said they have no problem driving their kids to school, they just want a heads up when they have to.

"They should have let us know ahead of time that they were having problems with the buses and also bus drivers," Tyler said.

JPS officials said students affected will be allowed to make up missed classwork.
